Since revision 7eab8e26
the `_onchange_partner_id` of `account.invoice` failed
if the SUPERUSER created an invoice for another company
than his own, and if the partner had not a specific
receivable or payable account (meaning the default
accounts are used, the accounts coming from the properties
of this company without any partner specified)
because
```
prop.search([
             ('name', '=', 'property_account_receivable_id'),
             ('company_id', '=', company_id)
            ])`
```
can return multiple records, if several partners
have their own receivable accounts set, and,
since the above revision,
`get_by_record` specify `ensure_one`, meaning
you cannot pass multiple records to this method.

This domain was built a the time
(2009, rev. 80861660)
to handle the multi-company property,
which can now be handle with a simple `force_company`
passed in the context. It was not the case at the time.

This revision could be applied in former releases,
but this is not a necessity. This is a necessity
in saas-10, because of the above revision.

A read more was added to every node having a mail-quote tag.
However all quotes and their child nodes are tagged, leading to numerous unnecessary read more / read less.
Now, all consecutive mail-quote are joined in one 'read more/read less'.

When going over the colorpicker when no bg-* class was selected yet,
the bg-undefined class was added on the snippet.
Also, when clicking on the reset button, the bg-* class was removed
but the selected button in the colorpicker was not unselected.

To be able to counter part the expense of the employee with the account set on his personal contact form, we need to configure the 421 account as payable.

On the font-end view of project.issue, only the messages of type `note` were
display. This excluded the messages recieved via email which makes hard to
understand a conversation (e.g. a customer does not sees his own answers).

Instead, only filter out the notifications (change of states, responsible...)

Using groups when declaring an extension of an asset bundle leads to a
different generated asset bundle according to the user's group. This
is not something we want because a dynamic asset bundle's content
means that it could (and it does) trigger unwanted cache invalidation.

website_event, website_blog, website_forum and website_sale add
functions to `website.contentMenu`. These functions are bound to
server side qweb nodes protected by groups. We can always add the
functions; if a user tries to use the routes he should receive a
traceback because of lack of access rules

website_blog adds a `website_blog.editor` module, but is guarded by
the presence of a node in the DOM. We use the same logic to guard the
module added by website_sale with the `.js_sale` node.

website_gengo is working as expected.

Currently on mobile, the livechat window would take all the viewport of
a small screen mobile browser. This combined with the "auto open"
feature can be desorienting: users could have only seen the "hello, how
may I help you ?" window and not know what to do or what is happening.

So this commit remove the "auto open" feature if user is on a too small
device (the user would thus have to click on "Have a Question").

When creating a new invoice through the web interface,
a bunch of "default" values are loaded once the partner
chosen, thanks to an onchange on this field,
such as the `account_id`, the fiscal position, etc.

It was not when importing an invoice, making it
more difficult to import an invoice.

In addition, the taxes lines were not computed at all
when importing an invoice with taxes within its
invoice lines, while it should be the case
if the tax lines are not forced during the import.

Otherwise it is not visible when set on an instance of the new API.

Without this patch a low priviledge user was not able to modify its own value

This reverts commit d780f947.

Did not work due to the size=3 on name field that strips the code to the first
three letters only (removing the " (copy)" part).
Copying a currency has a few business cases as the rates are not copied.
As can not increase the size of a field in stable, remove the method that had no
effect.

And avoid bug with negative ids to happens in the first place

The mimetime fetching in /web/image/... may fail if:
- calendar is installed
- `id` is a string (using ?id=42 in the URI)
- `id` is a negative number (company partners on odoo.com)

The `search` override of `ir.attachment` in calendar detects if a number is a
virtual ID when it contains a '-' and is a string.

While it is not optimal to allow both int and str format for paramter `id`, make
the verification of virtual ID in calendar more strict to only match the format
`<real>-<virtual>` and not `-<real>`

642fea43 updated some models to new API but this was not taken into
account into the part of the code this commit fix.

This `,` at the end creates a tuple and `if (False,)` will be evaluated to True.
This leads to invalid `Notification Email`.

Hum..

When we download a file (as can be done with attachments in Odoo),
firefox is opening the link in current window but cancel the action once
it is aware the resource is to be downloaded.

But this get firefox into a corrupt state for some contenteditable
features, for example document.queryCommandState which is needed for the
editor will after downloading a file throw an error consistently instead
of working as expected.

It can be reproduced on firefox (at least from version 32 to 46) with
the following snippet:
 https://jsfiddle.net/s246u3ay/3/

The issue is probably linked to the following reported issue since 2005:
 https://bugzilla.mozilla.org/show_bug.cgi?id=297494

This commit avoid the bug by opening attachments download links in a new
window instead of the current one.

Thanks to @rim-odoo for its grammar extremist review, and @tde-banana-odoo for our long debates about wizard conventions.

The company logo file extension is always '.png', even if the logo is of
another type such as 'jpg' or 'gif'. This is not an issue for decent
browsers, but IE might not display the image under specific
circumstancies, e.g. in combination with nginx.
